Patent JP-2000506029-A (JP)
IPC: A61L2/24
Filed: 1997-02-11
Abstract: The invention is a system and method for real-time monitoring and control of sterilization cycle parameters within a load-simulation device that simulates the same conditions as those within an acceptable standard challenge load to be sterilized. Integration of the device into the sterilizer control system allows critical sterilization parameter levels to be achieved and maintained within the simulated load throughout a sterilization cycle, thus resulting in a significant reduction in the number of unsuccessful cycles. A redundant parameter-monitoring system within the device is included. When acceptable sterilization parameter levels are shown to have been met, the sterile load is automatically released for use immediately upon completion of the cycle, thus eliminating the need for biological indicators and chemical integrators.

Patent JP-2001508873-A (JP)
IPC: G04B37/08
Filed: 1998-01-19
Abstract: This invention relates to a rubber plate (elastic) (FIG.1) which, when soldered at its edges (FIG. 1A) to the inside of the body (case) of a watch (or other object) (FIG. 3A), totally seals it against water and dust. At the same time, in view of the fact that it is soldered at its sides (edges), its central part remains totally free, thus permitting the movement of the outside control buttons (FIG. 4C, D and 6A) and activating the mechanism, whether it is electronic (FIG. 3D) or mechanical (FIG. 5 and 7) (digital or analog). When the external controls are pressed, the corresponding function is switched on internally (FIG. 4E, F). A single plate (FIG. 3A) can be used for various controls (FIG. 3B, C) or one plate for each control (FIG. 4A, B), depending on the distance between them and the space available in the watch-case. This system, which involves extremely low costs, is not exclusive to watches and can be used for any instrument that is intended to be placed in deep water or where a lot of dust is present (or non-corrosive liquids), for example stopwatches, cameras, video cameras, floodlights, underwater weapons, etc., without the risk of any penetration, even at a great depth.
